12 Video and Key
Note: For Video & Key the DLNK-2K option is required. This is now a standard option on the
V1-HD-2K model.
There are two methods to record Video & Key:
 Single-pass Recording using two synchronized inputs.
 Dual-pass Recording using a single input and the V1-HD Merge function.
In both cases, the end result is a single file with locked Video & Key outputs.
In addition to the video, and regardless of the bit-rate used: the V1-HD records 2, 4, 6 or 8 tracks of
uncompressed audio (sampled at 48 KHz).
Analog and AES audio are at 16-bit depth; The SDI embedded audio is at 16-bit or 32-bit depth; The
V1-HD also records LTC and ATC time-code.
The V1-HD records in different ways depending on the Time Code Mode selected in MENU (2). The
V1-HD does not allow for repeating or non-continuous time-code.
The file time-line starts at 0 and ends at 24hrs.
 When Time Mode is set to Time Code, the V1 will read the incoming time code LTC or ATC
depending on the time-code selection in OPTION MENU (17) and synchronizes itself to
record on the time-line and at the proper position.
 When Time Mode is set to A-Time, the V1 will record on the time-line at the current position
or at the end of file depending on the “Rec at:” setting in OPTION MENU (01) “Transport”.
